08 - SUPERTRACK H: Package Split Review (PKG-A..I)

Checks

check	result
packages not too broad	PASS - each maps to a coherent S-range; DDL / DATA / rehearsal / repoint / cutover / freeze are distinct packages
packages do not mix unrelated authority layers	PASS - "No package mixes layers" stated and held
author-only packages do not include apply	PASS - PKG-A/B author-only; PKG-C rehearsal BEGIN..ROLLBACK; PKG-D read-only
production-mutation packages operator-gated	PASS - PKG-E..H all who: OPERATOR
Codex re-audit before dangerous packages	PASS - re-audit gate before PKG-D and before PKG-E (the first production-mutating package)
package dependencies explicit	PASS - linear chain with named predecessors
each package has no-go, rollback, validation	PASS - all nine present
package names match construction order	PASS - PKG-A..I map to S01-S19 ranges
no package secretly enters Stage 2.6B	PASS - explicit "Stage 2.6B is NOT a package here"
no package can open permit/REAL_RUN/QT001 apply	PASS - all three excluded from every package; PKG-I notes they remain separately gated

Finding

XHD-01 (P2) - PKG-G no-go (also a Directus finding)

• Detailed in doc 04. PKG-G no-go now includes app-table authority loss + unverified snapshot.
• Also added G-DOT-NOOVERWRITE to PKG-E validation (the control plane is owner-isolated at creation, so overwrite-immutability should be asserted when it is first created).

Independent rigor check - sequencing gate adequacy

The chain PKG-A->B->C --[Codex re-audit]--> D --[Codex re-audit + permit]--> E->F->G->H->I places a fresh Codex re-audit before the first read-only proof package (D) and again before the first production mutation (E), each with a permit at E. This matches the FIX-history discipline ("fresh independent re-audit before any apply"). No package can self-escalate: the OPERATOR who + permit preconditions are explicit. Adequate.

Verdict

PACKAGE_SPLIT_PASS_AFTER_FIX - dependency-safe, layer-clean, operator-gated where mutating, Codex-re-audit-gated before dangerous packages, with the no-go gap fixed.
